JOSEPH MUIR, OF NEW YORK, N. Y.

MACHINE FOR CONDENSING PAP 0R SLOPS 0F CLAY FOR POTTERS USE.

Specification forming part of Letters Patent No. 45,736, dated January 3, l865.

To all whom iv' may concern:

Be it known that I, JOSEPH MUIR, ot' the city, county, and State ofNew York, have invented a certain new and useful Machine for Oondensing the Pap or Slops of Clay for Potters Use; and I hereby declare that the followingis a full and correct description thereof, reference being had to the annexed drawings, making part ot this specification, of which- Figure l is a plane view of the machine; Fig. 2, a sectional elevation. Figs. 3, 4, and 5 represent modifications ot' parts of the machine.

My said machine consists ofa whirling-vessel combined with mechanism for rotating it, the whirling-vessel being of circular form, for condensing the pap or slops of clay for potters use when the same is placed therein in proper quantities and iubjected to its operation, substantially as hereinafter described, but more particularly to describe said machine, I will refer to the drawings by lette-rs of reference.

Letter a represents theframe; letter b, avertical shaft stepped in across-bar, c, atthe bottom of thefra me, and provided with tight and loose pulleys, d and d'. The upper part of the shaft runs in a bearing fitted to it, and carries a i1 n'izontal disk or platform, e. Upon this platform is the'whirlingvessel, f, secured to the platform by screw-bolts g and g', or in any other convenient manner; A pipe, It, leads from the center ofthe vessel, at the bottom, outward to its periphery, and is closed at the end by the screw plug q, or in any other convenient manner. This pipe may be dispensed with, and in its place a hole may be made in the center ofthe vessel, communicating;l with a hole in the shaft, or a pump or siphon may be u sed to draw oit the water. At the top ofthe vessel the sides tumble or incline inward, to prevent the material from being thrown out of the vessel and to coniine it to the sides thereot'. 'lhe sides of the whirling-vessel should be iinperforate and impermeable to water, in order to prevent the escape thereof through the sides during the operation ofthe machine.

At Fig. 3 of the drawings, wings i' are shown .about one third full.

by dotted lines, which may be attached to the sides. There are also shown, at Figs. 4 and 5, different forms ot whirling-vessels which I have used to advantage, but I prefer the forms shown at Figs. 1 and 2.

'My said machine is designed to be used in carrying out an improvement in the process of preparin clay for potters use. In operating the machine for this purpose the slops or pap is placed in the whirlingvessel until it is The vessel is then set in rapid motion bythe rotating mechanism, and the centrifugal force com munieated to the mixture throws it out from the middle of the vessel and against the sides thereof, to which the clay adheres by reason of its adhesiveness, the water falling back to the middle of the vessel when the motion is stopped, from whence it may be removed in any ofthe ways before mentioned, and the clay may then be taken from the'vessel in the plastic state to be used by the potter, or it may be solidicd by evaporation and prepared for market as potters clay, in the usual manner.

It is necessary that the sides ofthe whirlingvessel should incline inward at or toward the top, or, if the sides be perpendicular, that they should vhave a rim at the top projecting inward, for the purpose of preventing the inaterials fron being thrown out.

I claim- 1. The whirling-vessel having imperforated sides, impermeable to water, and inclining inward or with a rim at the top, and combined with mechanism for rotating it, substantially as described and substantially for the purposes hereinbet'ore set forth, and with thedraw oft' pipe h, or its equivalent, in combination with the whirlingchamber.

2. Securing the whirling-vessel to the rotating mechanism by means ot'adisk or platform, 6, and the screw-bolts g and g', or their equivalents, for the purpose ot conveniently attaching or removing the whirling-vessel.

JOSEPH MUIR.
